Opinions on preamps


I am considering upgrading my pre amp. My system is as follows:
Sonic Frontiers SFL2
VAC Renaissance 70 MKlll
Klyne 7 PX3.5 phono
Verity Parsifal Encores
Basis Debut
Graham 2.0
Clearaudio Accurate
Dedicated room with much attention to details (wires, set up, isolation)

The weak link in my system is the SFL2 preamp. I am considering the following:
BAT 30SE
BAT 50SE
Wyetech Opal
Hovland
Emotive Sira

Anyone familiar with these items.
Your thoughts would be greatly appreciated

Thank You

Foundation Research is a small company in Canada that produces amps, preamp, noise loads for speakers, and passive in-line power conditioners.

I've heard on several occassions that FR's new tube pre-amp the V6 has far exceeded any competition at audio shows around the Toronto area. I think it goes for about $5k - $6k.

I own three of Foundation Research's in-line passive power conditioners LC-1's and LC-2 and believe them to be a superior product.

-IMO
What makes you think the weak leak is the SFL-2? Have you tried different tubes, and you're obviously into LPs, why not try a tube phono stage.

You've also got a 4 ohm loudspeaker, no 65 watt tube amp is going to put out enough current into that load. Have you tried bigger amp.
I would suggest that you also consider the First Sound line up of preamps. I have a Paramount and have been extremely happy with it.
I would suggest the Opal. I have found this preamp to be a very quiet, excellent performer.It's build quality is topnotch and it's soundstage is very robust and lifelike. Although it's a tube preamp, it is not overly rich or warm sounding.I use it with SS mono-blocks, but it would be just at home with your VAC.Based on your comments about isolation and a dedicated room, I think you would be very pleased with the Opal's presentation, finesse,frequency response, clarity,top to bottom extension and it's ability to produce low frequency tones with definition & body.(You should hear an acoustic bass in a jazz trio!!)
